Excerpt

OMC Setup

This is the only command you need to learn. After running this, everything else is automatic.

When this skill is invoked, immediately execute the workflow below. Do not only restate or summarize these instructions back to the user.

Note: All ~/.claude/... paths in this guide respect CLAUDE_CONFIG_DIR when that environment variable is set.

Best-Fit Use

Choose this setup flow when the user wants to install, refresh, or repair OMC itself.

Marketplace/plugin install users should land here after /plugin install oh-my-claudecode
npm users should land here after npm i -g oh-my-claude-sisyphus@latest
local-dev and worktree users should land here after updating the checked-out repo and rerunning setup
